To move a repository from one server to another you will want to use the svnadmin dump and svnadmin load commands.

Subversion provides such functionality
by way of repository dump streams. A
repository dump stream (often referred
to as a “dump file” when stored as a
file on disk) is a portable, flat file
format that describes the various
revisions in your repository—what was
changed, by whom, when, and so on.
This dump stream is the primary
mechanism used to marshal versioned
history—in whole or in part, with or
without modification—between
repositories. And Subversion provides
the tools necessary for creating and
loading these dump streams: the
svnadmin dump and svnadmin load
subcommands, respectively.

The usage of svn dump is

svnadmin dump reponame > dumpfile

and the usage of svn load is

svnadmin load reponame < dumpfile.

The help page for VisualSVN that references the usage of svnadmin dump can be found here and svnadmin loadhere.
